Communications Systems | PLE‑10M2‑EU Plena Mixer

The Plena mixer is a high performance, professional publicaddress mixer with modern state of the art features.Combined with the PLE-1P120-EU or PLE-1P240-EUamplifiers, you can build an easy-to-operate yet powerfuland flexible public address system. All this withoutsacrificing features such as ducking, priority, and flexibility.The mixer fulfills a wide variety of public addressrequirements yet is surprisingly affordable.

Functions

InputsAll Mic/line inputs can be switched between microphonelevel and line level sensitivity. The inputs are balanced andcan also be used unbalanced. Phantom power can beswitched on to provide power to condenser microphones.

Input channels 1 and 2 can take priority over all othermicrophone and music inputs:

• Input 1 can be activated by contact closure on the PTT(push to talk) input, or the input can be switchedautomatically if a signal is fed to the input, i.e. ifsomeone speaks into the microphone (VOX activation).A 2-tone chime can be configured to precede anannouncement

• Input 2 also has a VOX possibility. When one or bothinputs are configured for priority, the attenuation(reduction) of the cinch input can be set between ‑2 dB(little attenuation) and -∞ dB (mute). This provides atalk-over or voice-over function.

Input channels 1 and 2 also feature selectable speech filtersto enhance the clarity of announcements.

Labels and colored pinsMore unique features are available such as a detachablelabel where the user can write the names for inputs, musicsources and zones. These labels can then be mounted onthe front, protected by the clear window.

Another useful feature is to indicate preferred settings onthe front panel by inserting colored pins at the preset levelsof all knobs. You can then instruct a user to set all thecontrols to the green pins to configure the system for theirparticular use. A second user can set all controls to the redpins for their configuration.

Unique featuresSeparate music inputs are available with their own inputselector, volume control and tone control. The user canchoose a music source such as a CD player or radio (like thePLN-DVDT), and set the music level. A desired sound for themusic source can be set separate from the mic/line inputs.So if the music requires boosted low frequencies, themicrophone voices will still be clear – a truly unique featurein its class.

The tone controls also have the following unique features:

• The mixer features separate tone controls for mic/lineinputs and music inputs so the microphone voice canbe specifically optimized for excellent speech or singing

• The tone controls for music enable the most suitablemusic reproduction

In addition, the tone controls are not standard bass andtreble controls; our experience has enabled us to develop atone control that can be used as a traditional tone controlwith high and low control, but with a powerful contour thataddresses the problems that are found in real situations.

The tone control for the microphone and line inputs:

• boosts warmth in voices without boosting rumble, andcuts rumble without losing warmth in the lowfrequencies

• boosts sparkle without adding sharpness in the highfrequencies when boosting, and reduces harshness andsharpness without reducing clarity when cutting

The tone control for the music inputs:

• boosts deep bass first without making the sound hollowor boomy, and cuts rumble without losing warmth in thelow frequencies

• boosts sparkle without adding sharpness in the highfrequencies, with slightly different frequencies to suitmusic reproduction

IntegrationA telephone / 100 V emergency input with VOX activation isprovided for easy integration with another PA system or atelephone paging system. It has its own preset volumecontrol and overrides all other inputs, including call stationand inputs 1 and 2.

ZonesThe mixer has two zone outputs. The music can be switchedon and off in the zones via the front panel and optional wallpanel. Announcements from the PLE-2CS two-zone callstation can be routed to zone 1 or zone 2, or both.Announcements from the tel/100 V input or inputs 1 & 2 arerouted to both zones. Input 1 can be used for a PLE-1CS all-call call station or any other microphone or call station witha PTT contact. The unit also has a line output to connect thepre-amplifier output before zone selection, making itpossible to create a third zone. This output can be switchedto music only, for example, so that music on hold can beprovided for the telephone system. Loop-through input andoutput connections enable external sound processingequipment (e.g. an equalizer or Plena feedback suppressor)while maintaining a balanced connection to the amplifiers.

Output statusAn LED VU meter monitors the master output. A headphonesocket, below the VU meter, provides the mixer outputbefore zone selection so you can listen to the output beforethe signal is sent to the zone.
